Sigur’s appeal is easy to understand. He is reportedly valued for his ability to play as a deeper midfielder, operate slightly higher, and cover at right-back if needed. That kind of versatility matters at Celtic, where domestic pressure and European demands can stretch a squad quickly.
There is also a profile fit here. Celtic have often looked for players who can contribute now but still carry development value. Sigur appears to sit in that bracket. The report says he would also welcome the chance to play club football alongside Alistair Johnston, a familiar connection that could help any transition.
The timing is notable. Arne Engels has been linked with a move away, and even if nothing is settled, that kind of noise can shape a club’s planning. Smart recruitment teams do not wait for a departure to become official before mapping the replacement market.
That may explain the parallel interest in Gvidas Gineitis. If Celtic are examining more than one midfield option, it points to a broader attempt to protect depth rather than chase a single name.
This does not look like a one-position window.
The key now is whether interest in Sigur turns into formal negotiation. If Celtic can settle the midfield picture early, the rest of the window should become clearer - and the next storyline will be whether this is about strengthening from a position of power, or preparing for a significant exit.
